Specification of Letters Patent.

Patented Jan. 25, 1921.

Application filed October 13, 1919. Serial No. 330,390.

To all whom it may concern:

Be it known that I, J osnrrr S. RINscHLnn, Jr., citizen of the United States, and resident of New York city, in 'the county of New York and State of New York, have invented certain new and useful Improvements in Jars, of which the following is a specification.

This inventionrelates to jars, and particularly to the kind adapted for preserving perishable food or the like.

One of the objects of my invention is to provide a simple, inexpensive article which may be easily cleaned and emptied, thus complying with the usual sanitary requirements.

Gther objects of this invention are to provide inexpensive and dependable means for airtightly sealing such jar without resorting to the use of gaskets or washers of any sort, and for preventing its voluntary opening.

Still further objects will be more fully apparent from the following description and the accompanying drawings, forming a part of this specification, in which:

Figure 1 is the top view of an open jar.

Fig. 2 is an elevation of an open jar, partially in section.

Fig. 3 is a detail view, in section, of a portion of a covered jar.

Fig. 4: is a top view of a portion of a covered jar.

Fig. 5 is an elevation of a ar cover, partially in section.

Fig. 6 is a detail view in section of a part of the jar cover, showing a centering lug.

Fig. 7 is a partial detail bottom view of the cover. 7

Referring to the drawings, the jar body 10, made preferably of glass, but which may be made of any suitable material, is of true cylindrical shape and possesses near its open end a channel-formed annular receiver 11 into which may be poured a. liquefied sealing medium such as wax, paraffin, or the like, as indicated at 12.

A cup-shaped cover 13 fits into the receiver 11 in such a way as to equally distribute the molten sealing medium on both sides of the depending portion 1 1 of the cover. In order to assure the cover fitting nearly concentrically around the upper portion 15 of the jar without permitting the inner cover wall to touch the outer jar wall, and the outer cover wall to touch the inner receiver wall 16, a plurality of centering lugs 17 are provided at the inner cover wall in such a way as not to interfere'with the free circulation or unobstructed distribution of the sealing medium within the receiver 11.

At the lowest part of the depending portion 14: of the cover a plurality of passages or notches 18 are provided for facilitating the free flow of the molten sealing medium to both sides of the cover. These passages serve not only for the above mentioned purpose but they also prevent the cover from voluntarily turning or becoming loose, when the fluid sealing medium has hardened and forms a solid mass. For similar purposes recesses 19 are provided at the bottom of the receiver 11. The liquefied sealing medium enters these recesses and, when solidified again, is prevented from voluntarily turning in the receiver 11. In order to anchor the medium and prevent its moving out alongside of the cylindrical jar, lugs 20 are provided near the bottom of the reoei-yler and form an integral part of the jar wa Similar means 21 provided upon the cover prevent the latter from voluntarily leaving the receiver when the sealing medium becomes solid. It is understood that instead of recesses 19 lugs may be provided, and that instead of lugs 20 and 21 grooves may take the place of these anchoring means.

The use of my jar is obvious. After filling the jar with the material which is to be preserved, a liquefied sealing medium is poured into the receiver 11 and the cover is immersed in the medium. lVhen solidified the latter will not only absolutely seal the jar but prevent the cover from voluntarily leaving it.

When it is desired to uncover the jar, a simple cutting of the sealing medium around the outer wall of the cover usually suflices to loosen the cover enough to allow it to be removed. In order to make this operation still easier, the sealing medium is liquefied again and the cover may be then removed.

Having thus described my invention I claim:

1. A jar having a cylindrical body, an annular channel formed around the body near its open end for receivin a sealing medium, a cover arranged over t 1e open end of said body with a depending portion fit ting within and spaced from the walls of the annular channel, said depending portion having notches therein to receive the sealing medium whereby the cover is locked in position.

2. A jar having a cylindrical body, an annular channel formed around the body near its open end for receiving a sealing medium, a. cover arranged over the open end of the body with a. depending portion fitting within said channel and spaced from the walls thereof, and means on the depending portion of the cover for engaging the sealing medium whereby the cover is looked in position.

8. A jar having a. cylindrical body, an an- 15 nular channel formed around the body near its open end for receiving a sealing medium, a cover arranged over the open end of said body with a depending portion fitting within said annular channel and spaced from its walls, and means associated With the annular channel and also the depending portion of the cover for engaging the sealing medium JOSEPH S.
